Divided and this application filed May 23,1929. Serial No. 365,369.

The invention relates to feeding devices for, feeding paperor otherstock through a ma.- chine to accomplish work upon the stock; Theinvention is herein shown and described as applied to printing pressesas disclosed in my copending applications respectively designated SerialNo. 7l1,428, tiled October 3, 1924 and Serial No. 302,831, filed August29, 1928 of which this application is a division.

The invention has as one of its principal obj ects the provision of aconstruction capable of association with one of a pair of cooperatingrollers, to which the stock is fed and the provision of means providingfor angular and longitudinal adjustments of an element of thestructureto thereby accomplish proper holding and feeding of stool; of variousdimensions.

Another object of the invention is the provision of an arcuate resilientelement capable of association with a roller, to thereby provide meansto assist in frictionally holding said element against displacementrelatively to said idler.

A further object of the invention is the provision of an element such asjust described having means which, when applied to the roller, assiststo hold said element against relative rotation with respect to theroller. The invention has as another object the provision of a rollerhaving means with which the holding means of the resilient element maycooperate to prevent relative rotation, said means of the rollerpermitting longitudinal adjustment of said element with respect to theroller.

The invention has these and other objects, all of which will beexplained and more readily understood when read in conjunction with theaccompanying drawings which illustrate one embodiment of which theinvention is susceptible, it being obvious that changes andmodifications may be resorted to without departing from the spirit ofthe appended claims forming a part hereof.

In the drawings, Fig. 1 1s a SBCtlOllfll new of a portion of a prlntingpress showing a type or printing roll and an impression roll the formerhaving the invention applied thereto;

Fig. 2 is a front elevation of the type or printin roll shown in Fig. 1;

Fig. v3'is a section taken on line 3-3 of Fig. 2; and Fig. 4 is aperspective view ofthe feeding ring.

The invention is herein shown and described as'appliedzto the type orprinting roll of a printing press, the latter of which is arranged tocooperate with an impression roll. One of the elements employed in thefeeder is generally designated 10 and is mounted upon a roller such as11 to provide means to assist in the feeding of paper be tween theprinting roll 11 and the impression roll '12. The element 10 ispreferably formed as clearly shown in Fig. 3 to provide an arcue atesplit resilient ring which is adapted to be associatedwith the printingroll 11. This arcuate or split resilient ring is in the present instancetypehigh and-cooperates with the impression roll 12 to feed the stockbetween the rolls 11 and 12, and extends throughout more than 180 of thecircumference of the roll 11 so that it will clamp the roll and therebyfrictionally hold the ring with relation to the roll. The ring has aninwardly extending-lug or extension 13 provided to cooperate with meansprovided in the roll to prevent rotation of the ring with respect to theroll when said ring is associated with the roll. The means of the rollabove referred to for preventing relative rotation of the ringcontemplates the provision of a plurality of circumferentially arrangedgrooves 14 which extend longitudinally of the roll and provide means forthe reception of the lug or exten sion 13 of the ring to thereby providea means with which the lug may cooperate to prevent rotation of the ringwith respect to the roll. By providing these longitudinal grooves 14, itis manifest that the split rings 10 may be adjusted longitudinally ofthe roll to thereby arrange said rings so that they will properlycooperate vwith sheets, envelopes, etc., of various widths. Thesegrooves 14 are arranged circumferentially of the printing roll to permitthe ring to be adjusted angularly with relation to the roll and therebypermit of adjustment to insure the feeding of stock of different lengthsthrough and between the printing and impression rolls. These groovespreferably extend from end to end of the roll and thus allow the ringsto be associated with the rolls by passing said rings over the end ofsaid rolls.

From the foregoing description, it is manifest that an extremely simplearrangement is provided for engaging and feeding stock between rolls tohave work performed thereon and in which an element of the feedin meanswhich engages the stock is adjustab e both angularly and longitudinallyof the printing ant impression rolls which will thereby allowadjustments to be made to compensate for and insure the proper feedingof stock of various lengths and widths.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An element of a feeding device including a roller, said elementconsistin of a sp 't ring having means formed tiereon for engaging theroller to provide for holding said ring against rotation relatively tosaid roller.

2. An element of a feeding device consisting of a split resilient ringhaving an end thereof formed to provide an extension for engaging aroller and providing means for holding said ring against rotationrelatively to said roller.

3. In a feeding device, the combination of a roller and an elementconsisting of a split resilient ring having means formed thereon forengaging the roller providing means for holding said rin and rolleragainst relative rotation, sai ring being movable longitudinally of saidroller with said means in functional engagement with said roller.

4. In a feeding device, the combination of a roller and an arcuateelement provided upon and frictionally engaging said roller,

i said element having inwardly extending means providing an element ofmeans for holding said element and roller a ainst relative rotation, andsaid element being movable longitudinally of said roller.

5. In a feeding device, the combination of a roller and an arcuateelement provided upon said roller, said roller and element having meansfor permitting angular adjustment of the element relatively to theroller and providing means for preventing relative rotation of saidelement and roller and permitting relative longitudinal movement of saidelement and roller.

6. A feeding device includin a roller and an arcuate member, said rollerhavin a plurality of circumferentially arranged longitudinally extendingmeans for engaging said member to prevent relative rotation of saidroller and arcuate member.

7. A feeding device including a roller and an arcuate member, saidroller having a plurality of circumferentially arranged andlongitudinally extending means for engaging said mem er to preventrelative rotation of said member and roller and providing meanspermitting longitudinal adjustment of said member relatively to saidroller.

8. In a feeding device, the combination of a roller and a splitresilient ring, said roller and split ring having means which cooperatewith each other providing means for preventing relative rotation of saidring and roller, said ring being contractible into frictional holdingrelation with said roller.

9. In a feeding device, the combination of a roller and a split springring adapted to be expanded to a1 range said ring for association withthe roller, said roller having a depression and said ring having meansfor engagin a wall of said depression to thereby provi means forpreventing relative rotation of said ring and roller.

10. A feeding device including a roller and a split ring, said rollerhaving a plurality of circumferentially disposed, longitudinallyextending grooves, the split ring having a projection for engagingeither of said grooves, said grooves and projection providing meanspreventing relative rotation of said ring and roller and providing moanspermitting longitudinal movement of said ring relatively to said roller.

In witness whereof, I hereunto subscribe my name this 9th day of May, A.D. 1929.
